Ernest
Rutherford was born on August 30, 1871 in Nelson, New Zealand. [1] He was the son of James Rutherford, a
Scottish wheelwright who immigrated to New Zealand in 1842, and
Martha Rutherford (née Thompson), an English schoolteacher who
immigrated to New Zealand in 1855. The couple had 12 children
total, of which Ernest was the fourth child. [2]
In 1893,
Rutherford graduated from Canterbury College with a M.A in
Mathematics and Physical Science. He earned his B.S a year after
by doing independent research. [3]
In 1894,
Rutherford won a scholarship allowing him to attend the
University of Cambridge. There, he worked as a research student
under J.J Thomson in the Cavendish Laboratory. [4] During this time, he worked on
developing a magnetic detector (a device he had begun working on
when he was in New Zealand). Eventually, he developed a device
that was able to detect magnetic waves from over half of a mile
away. Also, during his time in Cambridge, Rutherford began to
study radiation in uranium. [5]
In 1898,
Rutherford moved to Canada to teach physics at McGill University
in Montreal. It was during this time that he married
Mary Newton, whom he remained married to until his death. The
couple had one daughter, Eileen Rutherford. [6]
While in
Canada, Rutherford also continued to study radiation in uranium,
and discovered that there were two types of radiation, which he
named alpha and beta rays. [7] In
1902 Frederick Soddy and Rutherford proposed the theory of
radioactive change. Rutherford’s time in Montreal was very
productive, and he published between forty and fifty papers. [8]
In 1907,
Rutherford returned to England to teach physics at the
University of Manchester. In 1908 he received the
Nobel Prize in chemistry. [9] In
1909 Rutherford, Hans Geiger, and Ernest Marsden performed the
famous foil experiment, which was instrumental in developing the
current model of an atom. During his last year at Manchester,
Rutherford became the first person to deliberately transmute one
element into another. [10]
In 1919 he returned to
the University of Cambridge, this time as a professor of
physics. Rutherford
remained in Cambridge until his death, on October 19, 1937. [11]
